ABSTRACT:
The present invention is a multi-carrier communication system for transmitting/receiving signals via at least four sub-channels, comprising: a transmitter for transmitting data independently via the four sub-channels; a receiver comprising a receive unit disposed for each sub-channel for receiving data from a corresponding sub-channel and performing soft decision of the receive data; and means for inputting soft decision target values in receive units corresponding to three sub-channels other than a target sub-channel to a receive unit of the target sub-channel, wherein the receive unit of the target sub-channel adjusts its own soft decision target value using the soft decision target values that are input from the receive units of the other sub-channels, and decides the receive data based on this adjusted soft decision target value.
